Welcome to the series of courses on the conservation of two hundred outdoor plants I am the chief of flowers Today we are going to open the ninth class In the ninth class we are going to talk about azaleas, rhododendrons are a very important family potted plant, its flowers bloom tweeds are colorful, many flower lovers like to raise it. But in our family potted plants, rhododendrons are flowers that are more difficult to maintain. Many flower lovers first contact with azaleas, when they bought them back, they were very beautiful and ecstatic, but they did not raise them at home for a few days, and found that the flowers slowly withered, and most of the leaves also appeared black leaves and death, mainly because the rhododendrons were in the family potted plants, and the resistance in the trees and flowers was relatively weak. It is a relatively delicate plant, so if we know the habits of rhododendrons and can find out its habits, so that we can raise azaleas well. Then this course, will teach you in detail, the conservation habits and skills of all aspects of rhododendrons, let's take a look.
Lighting requirements
Let's first talk about the first conservation knowledge of rhododendrons, which is also a very critical conservation knowledge, that is, the lighting problem of rhododendrons. So in the family potted plant, how should we arrange the light of the rhododendron, understand the light of the rhododendron? Many flower friends have misunderstandings, especially for some novice flower friends, like to check the information on the Internet, the internet check will basically tell everyone that the azaleas are plants that like half yin, and then everyone raises according to this method, do not dare to let the azaleas bask in the sun, follow-up you will find that the azaleas have large areas of black leaves falling leaves, and the serious ones will directly hang seedlings. In fact, azaleas like the sun, especially when our family potted it. When it is said on the Internet that it is for wild varieties of rhododendrons, the environment on the mountain may not receive full sunlight, and it grows better. But now, after the domestication of various varieties and the transformation into potted plants in our families, the azaleas will be raised in a place with sunshine. Otherwise, the resistance will be very poor, the flowering effect is not good, the flower preservation effect is not good, and it is easy for black leaves to fall off. So tells everyone that our family potted rhododendron is to bask in the sun, and the more favorable it is to its health. That like this pot of rhododendrons, has always been raised in the sun, although there will be some small sun spots, but this does not affect its health, the follow-up it will germinate more buds, the buds will also hit more, the flowers will be more colorful, this is about the rhododendron light problem.
Watering requirements
The second is about the watering of rhododendrons, we water the rhododendrons to maintain a dry and re-watering principle, but there is a premise, that is, we want to raise it in a ventilated and sunny position, until the potting soil is completely dry, we directly water it. So how to judge whether the pot is dry, the most direct way is to touch the hand close to the soil, if there is no moisture on the surface of the soil, the pot is also very light, it means that it is dry, then it is necessary to immediately water it. to show you that after the soil is dry, the water must be watered thoroughly, until there is a continuous flow of water at the bottom of the pot, which means that the watering is thorough. Remember not to water half waist, must be watered thoroughly, watering does not have a fixed cycle, different seasons, different maintenance environment, different states of flowers, watering cycles will be different, we just need to remember, wait until the pot is dry, don't delay anymore, immediately water it thoroughly, keep dry and thorough watering methods, maintain such a habit, your rhododendron growth will be very good.
Soil requirements
The third is the soil problem of rhododendrons, rhododendrons are a very acidic soil plant, like weak acidic environment, here can give you a little knowledge point of science popularization, generally our family potted plants, most of the plants with large flowers and bright flowers are weak acidic. So our family potted rhododendrons, you can directly buy acidic soil on the Internet or in the flower and bird market for planting or changing pots, you can also use your own soil, if the family flowers are more raised, it is more affordable and cost-effective to match the soil yourself. Then every two or three months, it can be watered with a little bit of ferrous sulfate, so that the soil can be adjusted to be slightly acidic.
Requirements in terms of breathability
The fourth point is the permeability of rhododendrons, we can see that the leaves of rhododendrons are dense, the general leaf density of plants, the requirements for ventilation and breathability are relatively high, if you raise the rhododendron in a non-airable and breathable environment, it is easy to get sick and pests, then it will cause a large area of yellow leaves to fall off, the gain is not worth the loss. Rhododendron It is an evergreen tree, if there is a large area of leaf loss, it is necessary to consider whether the maintenance environment is too closed. So we maintain the rhododendron at home, try to maintain it in a well-ventilated location in our home, and the leaves and roots can grow healthily.
Fertilization requirements
Fifth point we will talk about the fertilization of rhododendrons, if your rhododendron is now growing healthily, the follow-up wants it to grow rapidly, the flowering effect is better, fertilization is essential. If you choose your rhododendron is now about to form a bud, or is forming a bud, or a part of the flower, some buds open, some do not open, these stages we can give it a fertilizer, is this potassium dihydrogen phosphate, which contains phosphorus and potassium fertilizer, if your bud has not yet formed or in the early stage of formation, we can use a gram of potassium dihydrogen phosphate with a liter of water, every seven days to water it. Then if part of your bud is open and part of it is not open, then we can use one gram of potassium dihydrogen phosphate with two liters of water to water it, which can increase its phosphorus and potassium fertilizer and achieve the effect of flowering.
Usually not in the flowering stage and period, we can use this quick-acting compound fertilizer, we can every twenty days to a month or so, sprinkle a little bit on its soil surface, and then every time it is watered, its fertilizer will be diluted into the soil, this is the azalea fertilization method all year round.
Well, this course on the conservation of rhododendrons has come to an end here, and I hope that this course will be helpful to everyone. Pay attention to to teach you to raise flowers.
